Not yet time for us... There's problems with U18.04 that render it unusable for our environment.

It's 10 nodes now, will be growing as we qualify the Slurm setup. The 'slurmctld' and 'slurmdbd' nodes are both running CentOS 7, so no advantage to consolidating on that (as well, may promote the slurmdbd node to be the Labs-wide Slurm DB host for multiple clusters...)
